The Oakland Raiders are planning to suspend wide receiver Antonio Brown after he reportedly “got into it” with general manager Mike Mayock.

Mayock fined Brown roughly $54,000 for missing team workouts in August, and Brown posted the disciplinary letter from the Raiders on social media and said the team was“hating” on him —which apparently led to the confrontation between AB and Mayock.

Mayock had also expressed displeasure with Brown for missing practices while dealing with his helmet issue — after the league told AB he couldn’t use his old helmet because it didn’t pass the NFL’s safety protocol. Brown had also missed time dealing with foot issues after he suffered extreme frostbite from a mishap in a cryogenic chamber.
